William Blaine Richardson III (November 15, 1947 – September 1, 2023) was an American politician, author, and diplomat who served as the 30th governor of New Mexico from 2003 to 2011. He was U.S. ambassador to the United Nations and energy secretary in the Clinton administration, a U.S. congressman, chair of the 2004 Democratic National Convention, and chair of the Democratic Governors Association (DGA). In December 2008, Richardson was nominated for the cabinet-level position of Secretary of Commerce in the first Obama administration but withdrew a month later, as he was being investigated for possible improper business dealings. Although the investigation was later dropped, it damaged Richardson's popularity and diminished his influence as his second and final term as New Mexico governor concluded. Richardson occasionally provided advice on diplomatic issues pertaining to North Korea and visited the nation on several occasions, including efforts to release American detainees. He completed a number of private humanitarian missions, one of which secured the release of U.S. journalist Danny Fenster from a Myanmar prison in November 2021.
